Pap Bombs

Just let the top bombs keep spawning and kill all the bottom ones. Eventually, Pap will be using the summon animation, but nothing will spawn. It's risky because when the clock dies, the final form might not appear due to the maximum monster population (or so I've heard).

Maximum monster population in a map type of glitch hasn't happened in a while. I don't believe you need to worry about it, unless the parent monster spawns multiple offspring on death.
